Application le. J'uly 19, 1919. Serial No. 311,986.

T0 all whom t may concern.'

. Be it known that I, WILLIAM W. G IL- Ln'rrn, a citizen of the United States, residing at Gloversville, in the county of Fulton and State of New York, have invented a new and useful Boiler, of which the following is a specification.

The present invention relates to steam generating boilers, the principal object being to provide a boiler wherein the water will be vapori'zed quickly and always maintaining the maximum of heat, and which is of such a construction as to be subjected to the highest degree of heat in the {ire-box.

A further object of this invention is to provide a steam generating boiler which includes an auxiliary boiler which is so arranged at the rear of the fire-box as to permit the heat to contact with the bottom and l both vertical faces, thus thoroughly vaporizing the water and always retaining the steam in live condition.

Another general object of this invention resides in the provision of a boiler construction which consists of few parts, which is simple in construction, and which may be manufactured and installed at a minimum cost.

With the above and other general objects and advantages in mind, the invention consists of combinations of elements, constructions and arrangements, operations and general assemblage, the details of which will be enlarged upon hereinafter and recited in the sub-joined claims, the invention being illustrated in the attached drawings, wherein Figure 1 is a side elevation of a boiler constructed in accordance with my invention and mounted in the usual fire box, the re box being shown in longitudinal vertical section;

Fig, 2 is an end elevation taken at the forward end of the main boiler; and

Fig. 3 is an end elevation of the auxiliary boiler.

Referring to the drawings, wherein like characters of reference' designate like parts in all of the views, the numeral 5 designates the usual fire-box provided with the usual bed 6 at the rear end of the fire-box.

The main boiler is designated at 10 and is of the horizontal tubulous type. This boiler is arranged so that its rear end projects slightly beyond the forward end of the bed 6.

Mounted within the fire-box and disposed directly over the bed 6 where the intensity of the heat generated in the fire-box is greatest, is an auxiliary boiler or tank 15 which has communication with the boiler 10 through the medium of a pipe 16 which leads from the end of the boiler into the upper end of the auxiliary tank or drum 15, and by means of water conducting tubes 15 located between the drum and boiler. A plurality of water supply pipes 17 lead from a water head 1S to the sideportions of the drum 15 to supply water thereto. A blowout pipe 19 communicates with the bottom portions of the boiler 10 and the drum 15, whereby mud or other sediment may be withdrawn.

From this disclosure it will be apparent vthat the drum is so positioned with respect to the boiler that the water contained therein will be thoroughly vaporized before the water in the boiler 10, thus causing the passage of steam from the tank or drum 15 into the boiler 10, thereby forcing the water contained in the boiler 10 through the pipes 17 and into the boiler 15, the steam generated tllways maintaining the highest degree of eat.

It is to be understood that the steam can be taken from the boiler at any desired point. For example the steam outlet pipe 16 can be extended from the pipe 16. A feed water inlet can be located wherever desired, as indicated for example at 18.

Battles 10 are interposed between the boiler and drum and serve to guide the hot products of combustion from the tubes in the drum and across the space between the drum and boiler to the tubes within the boiler.

The embodiment of the invention herein shown and described is the preferred construction, but it will be understood that the same may be modified and altered in many lrespects and that my limits of such modification are governed only by what is claimed.

What is claimed is 1. The combination with a tubulous boiler and a water head depending therefrom, of a drum supported beyond one end of and spaced from the boiler, said drum being tubulous, water pipes inclined upwardly from the water head to the drum, water and steam conducting tubes connecting the drum and boiler, said water conducting tubes being disposed between the drum and boiler, and baffles interposed between the boiler and drum to guide hot products of combustion from the tubes in the drum across the space between said drum and boiler to the tubes within the boiler.

2. The combination with atubulous boiler and a water head depending therefrom and -provided with a water intake, of a drum back of and in line with the boiler and spaced therefrom, said drum having tubes therethrough, baiiies interposed between the drum and boiler and constituting means for guiding hot products of combustion trom the tubes in the drum to the tubes in the boiler, inclined tubes connecting the header with the drum, water circulating tubes connecting the boiler and drum and located in the space between the boiler and drum, a combined circulating and blowout pipe connected to the bottom portions of the boiler and drum and opening outwardly therefrom, a steam pipe connecting the highest portions of the boiler and drum and having an outlet.

3. The combination with a fireboX of a furnace and a bed inclined downwardly and rearwardly back ofthe irebox, of "a boiler `above the reboX and a portion of the bed, a drum back of the boiler and above the bed and spaced from the boiler, said drum and boiler being in line, a water head depending from that portion ofthe boiler above the irebox, a water supply pipe opening into the header, water conducting pipes inclined upwardly and rearwardly from the header to the drum, said drum being Yspaced from the back wall of the furnace and having tubes for the reception of products of combustion, there being tubes within the boiler, baliies between the boiler and drum for guiding products of combustion from the tubes in the drum to the tubes in the boiler, water circulating pipes in the space between the boiler and drum and connecting said boiler and drum, a combined circulating and blowout pipe connecting the lowermost portions of the boiler and drum and opening outwardly from the furnace, and a steam pipe connecting the uppermost portions of the boiler and drum and having a steam outlet. In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.
